SPECIFICATION formingpart of Letters Patent No. 633,502, dated September19, 1899.

Application filed March 24, l899.

To all whmn it may cmccrn:

Be it known that I, HENRY B. CAMPBELL, a citizen of the United States,residingat Scranton, in the county of Lackawanna and State ofPennsylvania, have invented new and useful Improvements in Inkstands, ofwhich the following is a specification.

My invention relates to inkstands, and contemplates the provision of asimple and inexpensive inkstaud in which the ink will flow of itselfinto the dipping-cup and one embracing a dipping-cup susceptible ofadjustment, so as to present a proper quantity of clear ink to a pen,and simple, conpact, and efficient means for closing the dipping-cupwhen the stand is not in use in order to prevent evaporation and otherdeterioration of the ink and p reserve the same in a proper fluidcondition.

The invention Will be fully understood from the following descriptionand claims when taken in con junction with the anneXed drawings, inwhich Figu re 1 is a longitudinal section of an inkstank embracing myinvention. Fig. 2 is a plan View of the reduced portion of the reservoirwhich bears my improvements. Fig. 3 is a transverse section taken in theplane indicated by the'line 3 3 of Fig. 1 with the cover of thedipping-cup in its socket. Fig. 4 is a detail horizontal section takenon the line eL l of Fig. 1.

In the said drawings similar letters designate corresponding parts inall of the several views.

The reservoir A of the inkstand is formed in one piece of glass or othersuitable material and is provided with the usual reduced portion B and acircular opening O in the upper wall thereo'f.

D is an annulus, preferably of hard rubber, which is connected by cementor other suitable means to the upper Wall of the reduced portion Baround the opening C and is internally threaded,- as shown, and E is thedipping-cup, which is also by preference of hard rubber and isexteriorly threaded to engage the internal thread ed annulus D, and istherefore adapted to be adjusted vertically with respect to said annulusand the red uced portion B of the reservoir, for a purpose presentlydescribed. The said dipping-cup is provided at its upper edge with amarginal flange a, of

Serial No. 71o,36. (No model.)

curvilinear form in cross-section, calculated to prevent ink fromdripping from the dipping-cup upon that portion of the reservoirsurrounding the same, and it is also provided with a central andpreferably integral f unnel b, into which the pen is designed to bedipped.

The ink by reason of a well-known hydrostatic principle enters thefunnel b through the lower contracted end c thereof and rises to aboutthe height illustrated in Fig. 1. From this it follows that clear ink isalways presented to the pen, and it will also be appreciated that byadjnsting the dipping-cup with respect to the annulus D and the portionB of reservoir A the quantity or depth of ink eontained in the funnel I)may be increased or dininished to suit the pens and tastes of diiferentwriters For instance, when it is desired to present a considerablequantity of ink to the pen the dipping-cup is screwed downwardly, whilewhen it is desired to present a less quantity the said cup is screwedupwardly. v

In the dipping-cup, at one side of the funnel b, is provided avertically-disposed socket d, which is closed at its bottom and isprovided at its upper end and at opposite sides with stop-lugs e, asbest shown in Fig. 3. This socket when the inkstand is in use isdesigned to receive a cover F after the manner shown in Fig. 3.

The cover F, which is preferably of sheet metal, is provided at itsupper end with a knob f, which when the cover is in the socket restscoincident with a notch g in the top of the cup E, and may therefore bereadily grasped by the operator. At its lower end the cover is providedwith lateral trunnions h, which when the cover is raised in the socketare designed toengage the stop-lugs c, and thereby hold the cover to thecup and yet enable said cover to assume a position flat upon the upperend of the cup, so as to entirely and efiectually close the same, andthereby prevent evaporation and other deterioration of the ink in thestand. iVhen the stand is to be used, the operation described isreversed-that is, the cover is swung upwardly until it rests inalinement with the socket and is then dropped in the socket. From thisit will be seen that the cover F is permanently connected to theinkstandand is not liable to be inisplaced and IOO lost; also that Whennot in use said cover is entirely out of the Way, which is an importantadvantage.

It Will be observed from the foregoing that with all of its advantagesmy improved inkstaud is Very simple and enbodies but a minimum number ofparts, and may therefore be made and sold with profit for a pricealmost, if not quite, as low as that for which ordinary inkstands areoffered.

- Having thus described my invention, What I claim is- 1. In aninkstand, the con bination of a reservoir, a dipping-cup connectedthereto and having an opening and a vertically-disposed socket arrangedat one side of the opening and having stop-lugs at its upper end, and acover arranged in the socket and having latcral trunnions at its lowerend arranged to engage the stop-lugs, substantially as specified.

2. In an inkstand, the oonbination of the reservoir having the reducedportion and the opening in the upper Wall thereof, aninteriorly-threaded annulus fixed With respect to the reservoirandsurrounding the said opening` thereof, the exteriorly-threadeddippingcup arranged in the annulus and opening of the reservoir andhaving a funnel and a vertically-disposed socket at one side of thefunnel provided with stop-lugs at its upper end, and also having a notchin its uppen end conimunicatin g With the socket, anda sheet-metal coverarranged in the socket and having the tru nnions at its lower end andthe knob at its upper end, substantially as specified.

In testimony Whereof I have hereunto Set my hand in presence of twosubscribing witnesses.
